I would like to have a phone that didn't need a case. It should be drop tested to 6 feet or whatever the spec is and the screen shouldn't break. It should be water and dust proof and the screen shouldn't scratch easily in a less than ideal environment. I'm thinking of people who work outdoors, landscapers, laborers, mechanics, equipment operators, paving crews etc. People who could ruin a phone in their pocket from sweating on a 95 degree day.
I believe they have rugged versions of these.. they are bit bulky.. Moto turbo2 has a shatterproof phone if dropped from 5' but not sure how it would survive in more hostile environments. In any case, I'm glad Samsung has brought this back.. this is a good thing since Apple will feel like they need to do that do.. Competition is good!
